CRAJFE.

application filed March 23, 1922. Serial No. MMM?.

To all whom t may `conce/M1:

lBe it known that l, WALTER WAGNER, a citizen of Poland, residing atChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Carafes, of which the followingis a specification.

rllhis invention relates to certain new and useful improvements incarafes embodying a multiple wall metallic vessel having heat insulatingspace between the walls thereof,

said vessel being a wide bodied vessel having a comparatively slenderneck.

Carafes of this character have heretofore been constructed of glass orthe like with a separate metallic casing, and the manufacture of thesame incurred considerable expense and breakage of the same was anundesirable characteristic. lit is the primary object of this inventionto form the vessel entirely of metal which may be suitably enameled onthe interior and silver or nickelplated on the exterior as well as beingcomposed of a number of separate sectionspermanently, rigidly assembledin such manner as to present a neat and ornamental appearance and so asto provide for the ready and inexpensive manufacture of the same.

A further object of the invention is to provide an improved metal coverfor protecting the upper part of the neck of the vessel from rust andthe like and also to protect the enamel from being cracked by adding tothe ornamental appearance of the invention.

'A still further object of the invention is to provide a multiple wallmetallic carafe with a suitable packing between the walls thereof andmeans for facilitating withdrawal of air from the space between the walland preventing withdrawal ofthe packl("lhe invention embodies further imrovements in the art to which it relates an more particularly inconnection with the application filed by Walter Wagner on March 31,1921, Serial No. 457,361, allowed November 1, 1921.

A still further object of the invention is to generally implrove devicesof this character, whereby t e same may meet with all of therequirements for a successful commercial use.

Other objects will appear as the nature of the invention is betterunderstood, and the same consists of the novel form, combination andarrangement of parts hereinafter 0 more. fully described, shown in theaccompanylng drawings and claimed.

In the drawings, wherein like reference characters designatecorresponding parts throughout the several views,

Flgure 1 is a central vertical sectional view of the preferredembodimentof the invention with parts of the packing omitted for thesake of clearness, a handle being indicated by dotted lines,

Figure 2 is a vertical sectional view partly broken away of a sli htlymodified form of one of the inner wa ls of the carafe, and

Fi re 3 is a view similar to Fig. 1 of a modified form of a carafe.

Referring more in detail to the several views, the invention embodies aninner container including a metallic bowl-shaped bottom section 5 and anupper inverted substantially funnel-shaped section 6 with their adjacentmargins outwardly flanged and permanently united as at 7 through themedium of spot welding, solder or the like. These two sections of theinner container may be conveniently drawn from a sheet of metal and thetubular portion 8 of the upper section 6 forms a portion ot the neck ofthe vessel, the remaining portion of which is formed by the inner sleeve9 of a double walled top member 10 having a sccond sleeve suroundinglthe sleeve9 in spaced relation as at 11, and the sleeve 11 being oflesser length than the sleeve 9. The conneet-ing portion between thesleeve 9 and l1 is of annular form so as to provide an imperforatesmooth upper edge for the neck of the bottle, and the sleeve 9 isoti'set as at 12 to provide a shoulder or rest for the inturned edge 13of the upper section 15 of the outer wall of the carafe. As shown inFig. 2 the inner wall of the receptacle may be formed of a singlesection of material 5 in lieu of the upper and lower sections 5 and 6 asin Fig. 1.

The outer container of the carafe is formed of a bottom section 111similar to the bowl-shaped section 5 except that the section 14 is of alarger size so as to leave an annular space between the sections 5 and14 and the bottom of the section 1d is provide with a reduced annularportion 14 havii a flat bottom surface 14 so that the cara e may rest ina vertical position upon a table or the like. The outer container alsoembodies an upper section 15 ot substantially the same general form asthe section t et the (pending collar or sleeve 26 inner container,butfof uniformly larger size so as to leave a similar annular spacebetween the sections 6 and 15 about the neck portion 8 and the enlargedlow'er portion of the inverted funnel-shaped section'6, the s ections 14and 15 being joined at their margms by the provision of intertittingbeads. as at 16 and by soldering, brazing, orweldlng at this and similarpoints if found desirable. The beads 16 provide an ornamental jointbetween the sections 14 and 15, which .scctions may also be convenientlydrawn from sheet metal. The smaller or neck portion 17 of t-he outer andupper section 15 is rovided at a point spaced from its upper e ge withan annular corrugation'or bead 18 for purposes presently to bedescribed.

The adjacent edges of the inner sleeve 9 of the top member 10 and theneck portion 8 of the upper section 6 of the inner container are flangedoutwardly as at 19 and are permanently united through the medium of spotwelding, soldering or the like. The neck of the bottle is provided witha suitable closure or metal cap 20 which is of double walledconstruction and suitably constructed .of inner and outer permanentlyconnected and spaced Sections. The lower edge of the cap 1s adapted torest upon the corrugation or bead 18 of the neck 17 of the section 15 ofthe outer container.

Slightly spaced from the sections 14 and 15 of the outer container thereis provided an upper and lower section 21 and 22 of an intermediatecontainer. Similar to the upper sections 6 and 15 of the inner and outercontainer the upper section I21 of the intermediate receptacle isprovided with a reduced neck portion 23, the upper edge of whichsurrounds the overturned edge 24 of the outer wall 11 of the top member10 and is firmly secured thereto by welding,` soldering or the like. Theadjacent edges ofthe sections 21 and 22 are secured to each other as at25 in a manner similar to the securing of the adjacent edges vof thesections 14 and 15 of the outer receptacle. The bottom of the lower`section 22 is left open and is provided with a dedirectly beneath thebottom of the section 5.

An inverted substantially pan-shaped member 27 is fitted within thebottom opening of the intermediate lower section 22 and within thedepending sleeve 26 thereof. and it is secured in position inanysuitable manner as by means of solder or Welding, the top Wall of themember 27 is inwardly depressed to provide a central sleeve portion 28,the bottom of the sleeve portion 28 being closed by a bottom wall 29. Apair of perforated metal disks with a suitable fabric disk is disposedtherebetween as generally denoted by the numeral 30 and is firmly heldwithin the sleeve 28 and these disksroverlie' the opening ofa dependingsleeve 31 which is provided centrally of the bottom portion 29 which hasa suitable check valve 3-2 secured thereon by means of which air may bereadily exhausted from the space between the inner and intermediatecontainer of the vessel by proper connection with an air exhaustingdeviceand to permit the ready attaching of this air exhausting device tothe check valve 32, the flat bottom wall 14" of the section 14 has anannular opening 33 therein for receiving a plug 34; The space betweenthe inner and intermediate containers of the vessel is' preferablyfilled with a suitable packin of heat insulating material denoted Iiythe numeral 36 and the fabric and metallic perforated disks 32 permitthe exhaustion of air by preventing withdrawal of the packing. Theassembled carafe may be provided with any preferable form of llrandle 35shown in the views by the dotted lnes. f

In Fig. 3 I have shown a slightly' modilied form of carafe wherein themeeting,r edges of the upper und lower sections 6' ond 5 ofthe innercontainer' ere tolescoped and firmly united by soldering or the like.This same type of joint is provided between the adjacent edges of theneck 8 of the upper section of the inner container 6 and the lower edgeof the inner sleeve 9 of the top member 10. In this form of theinvention the sleeve 9 is offset as at 12 to provide a shoulder or restfor one end of a metal cover 13 which is employed for protecting theupper part of the neck from rust and for protecting the enamel of thesame from cracking. The upper and lower sections 21 and 22 in this formare substantially the same as the upper and lower sections 21 and 22 ofthe inner intermediate receptacle excepting that the meeting edges 25thereof are united through the medium of interlocking beaded edges. Theopposite end of the upper section 21 is also beaded as at 40 forreceiving the beaded lower edge of the protecting cover 13. The bottomof the vessel is formed by a pan shaped bottom forming member 41 whichtelescopes onto the sleeve 26 of the outer lower section 22 and whichlis suitably :fastened upon said sleeve 26 as well as being providedwith an annular bead 42 along its upper' edge for ornamental purposes.The pan-shaped member 27 in this instance is inwardly depressed toprovide a central sleeve portion 28', and a lower and larger sleeveportion 43 is connected by a horizontal annular portion 44, the bottomof the sleeve portion 28 being closed by a bottom wall 29 arranged inspaced relation to the portion 44.

From the foregoing description it is believed that the construction andoperation as well as the advantages of the present invention will bereadily understood and appreciated by those skilled in the art.
